This isn't the worst thing in the world, but I think it's part of the insidious bias the mainstream news projects on a near-daily basis. Check out the explanation of this story on CBS.com about Walmart coming into DC:.
There's nothing factually incorrect in it. The bias is not putting "living wage" in quotes or capitalizing it as a thing, as opposed to something else. Some people may read that as Walmart not wanting people to live, etc.
